Research on Compression Failure Characteristics and Damage Constitutive Model of Steel Fiber-Reinforced Concrete with 2% Copper-Coated Fibers Under Impact Load.

This study systematically investigates the mechanical properties of plain concrete (PC) and 2% steel fiber reinforced concrete (SFRC) under both static and dynamic loading conditions, utilizing advanced mechanical testing equipment and dynamic impact testing methods. The strain rate range studied spans from 10 s to 483.12 s.

Amplifying Sound Intensity of Key Words in Discourse Promotes Memory in Female College Students.

Purpose: The aim of this study was to determine whether amplification of key words in discourse helped to memorize the words.

Method: We tested the effect of 135 participants' memory for key words in the discourse after intensity amplification (0, 5, 7, 9, and 11 dB), and we also tested physiological indicators to measure attention levels in another 30 participants. Adobe Audition was used to modulate the intensity of key words, whereas E-prime technology was used to present speech stimuli and test the accuracy of the memory of the participants.

Age-dependent association of high urinary iodine concentration with major depression in adults: NHANES 2007-2020.

Excessive iodine exposure can have detrimental effects on thyroid function and overall health. This study aimed to investigate the age-dependent association between high urinary iodine concentration (UIC) and major depression symptoms in adults, using data from the National Health and Nutrition Examination Survey (NHANES) from 2007 to 2020. To perform stratified analysis by age, we utilized a rolling window method with a 15-year window width to examine the trend of the odds ratios (ORs) of UIC on depression symptoms with age.

sp. nov., isolated from the shallow-sea hydrothermal system off Kueishantao Island.

Strain designated TK19116 was isolated from the shallow-sea hydrothermal systems off Kueishantao Island in Taiwan, China. The bacterium was Gram-stain-negative, aerobic, oxidase-positive and catalase-positive. Cells of the strain TK19116 were short-rod-shaped and non-motile.

Cuproptosis-Related MiR-21-5p/FDX1 Axis in Clear Cell Renal Cell Carcinoma and Its Potential Impact on Tumor Microenvironment.

As a newly identified type of programmed cell death, cuproptosis may have an impact on cancer development, including clear cell renal cell carcinoma (ccRCC). Herein, we first noticed that the expression levels of cuproptosis regulators exhibited a tight correlation with the clinicopathological characteristics of ccRCC. The cuproptosis-sensitive sub-type (CSS), classified via consensus clustering analysis, harbored a higher overall survival rate compared to the cuproptosis-resistant sub-type (CRS), which may have resulted from the differential infiltration of immune cells.

Sulfoquinovose is a widespread organosulfur substrate for Roseobacter clade bacteria in the ocean.

Sulfoquinovose (SQ) is one of the most abundant organosulfur compounds in the biosphere, and its biosynthesis and degradation can represent an important contribution to the sulfur cycle. To data, in marine environments, the microorganisms capable of metabolising SQ have remained unidentified and the sources of SQ are still uncertain. Herein, the marine Roseobacter clade bacteria (RCB) Dinoroseobacter shibae DFL 12 and Roseobacter denitrificans OCh 114 were found to grow using SQ as the sole source of carbon and energy.

The Potential Role of Voltage-Dependent Anion Channel in the Treatment of Parkinson's Disease.

Parkinson's disease (PD) is a neurodegenerative disease second only to Alzheimer's disease in terms of prevalence. Previous studies have indicated that the occurrence and progression of PD are associated with mitochondrial dysfunction. Mitochondrial dysfunction is one of the most important causes for apoptosis of dopaminergic neurons.

Effects of M currents on the persistent activity of pyramidal neurons in mouse primary auditory cortex.

Neuronal persistent activity (PA) is a common phenomenon observed in many types of neurons. PA can be induced in neurons in the mouse auditory nucleus by activating cholinergic receptors with carbachol (CCh), a dual muscarinic and nicotinic receptor agonist. PA is presumed to be associated with learning-related auditory plasticity at the cellular level.

Overexpression of HOXC10 promotes glioblastoma cell progression to a poor prognosis via the PI3K/AKT signalling pathway.

Objective: The HOX gene is expressed in neoplasias occurred in multiple tissues, such as the colon, lung and breast. However, the effects of the HOX gene on glioblastoma (GBM) remain poorly understood. We examined HOXC10 expression in GBM tissues and cells, analysed its effect on GBM prognosis, and finally assessed its possible underlying mechanisms in this study.

Second dorsal metacarpal artery flap from the dorsum of the middle finger for coverage of volar thumb defect.

Purpose: The second dorsal metacarpal artery flap from the middle finger is a reconstructive technique that can be used to repair extensive volar defects in a normal-length thumb. However, few reports advocate using it for coverage of volar thumb defects. In this article, an anatomic study of 9 flaps used for resurfacing thumb defects is presented along with the clinical experience of the authors.
